CABLE-RAILWAY CONSTRUCTION,

SPECIFICATION forming part of Letters Patent No. 365,964; dated July 5, 1887.

Application filed March 12, 1887. Serial No. 230,705. (No model.)

To aZZ whom it may concern:

Be it known that I, ZAOOUR PRALL BOYER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cable-Rail way Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in cable-railway construction, and refers more particularly to my Patent No. 354,531, patented December 21, 1886; and it consists in various features of construction and arrange ment, which ,I will proceed to describe, and point out in the claims.

It has been found by experience in the construction of cable railways that it is sometimes necessary for two or more different railways to use the same street or streets, and it has also been developed thatit is desirable by each railway company, where different roads occupy the same street, that each railiroad use its own propelling-cable. It has a so been developed that where railroads already occupy streets which are desired to be .used by other railroads it has been found impossible to construct entirely different systems on same street, owing to the streets being narrow, and in some citiesthe law regarding railroads limiting the space as regards railroad-tracks. To this end I have devised the following construction of cable-railway systems.

Heretofore it has been that where separate railway companies occupied the same street they use different conduits and cables, or that one railway company uses the cable and conduit of the other company where it is desired to use so much of their road as may come on their line of route.

. By my invention two different roads may use the same conduit, each with its own tractioncable, and with an arrangement of track system which will take upbut a minimum additional track space.

In the drawings, Figure 1 represents a diagrammatic plan view showing the arrangement of tracks where two different railroads occupy the same street, a doubletraek system being shown. Fig. 2 is a perspective sectional elevation showing my improved conduit with track arrangement.

In the drawings, A represents the conduit, which is formed substantially as shown in my patent above referred to, except it is made wider and the yoke'arms a little longer.

B are the bracket-blocks, O the braces, D the sheet-metal casing, all of which are shown and described in my patent before mentioned.

. F is a central partition, which divides the conduit into two compartments, F F This partition is made of steel and formed with the channel portion F. This division-plate is securely fixed to the bottom of the conduit in any suitable manner, and is also braced by the horizontal plates G, which plates may be the journal -bearings for the cable-carrying rollers. The inclined upwardly-extending side flanges, f, of the channel-bar form each one of the slot-rails, the other slot-rail, H, be ing as shown in my former patent referred to. The track-rails I I are seated in chairs J J, and are securely bolted to same by brace-rods K K, as shown. The conduit, it will be observed, is embedded in a concrete base, and the part between the rails also concreted, and the pocket X of the channelbar is also filled with concrete,which allows a perfectly smooth surface andprevents any undue jarring or disarrangement of the conduit and slot-rails.

By referring to Fig 1, We will assume there are two different railways and explain their relation to each other. For convenience of reference, I will term one the W. G. Road and the other Traction Road. L 15 represents the streets upon which IV. 85 G. road runs. 17 L M represent the streets upon which the Traction road runs. It will be seen that the Traction road runs into L street at 17 and leaves L at M. The \V. & G. road runs from L to 15, as shown. It will thus be seen that the two roads occupy L street from 17 to 15. On this street the tracks of one road are arranged parallel, with about eight inches space between the rails. Between each set of trackrails are arranged the slots S S. At the junction of the two roads the wide double conduit is used until the roads diverge, when each takes its own single conduit again, the arrangement of such conduits being well understood by those skilled in the art.

It will thus be seen that by this arrangement several roads may run on one street in approximately the same space, and yet use different track-rails and different propulsioncables.

While I have shown my invention applied to a conduit, as shown in my previous patent, it may be readily adapted to any other style of conduit.

I claim- 1. In a cable traction railroad, the combination, with the cable-conduit, of a vertical division-plate suitably secured therein and forming two separate compartments, substantially as shown.

2. In a cable traction railroad, the combination, with the cable-conduiu'of a vertical division --plate, which is suitably secured therein, and whose top part is arranged intermediate of the outer slot-irons of a doubletrack system, substantially as shown.

3. The combination, with the yoke of a cable-conduit,of adivision-platesecured thereto,

said yoke and division-plate having slot-irons secured thereto, substantially as shown.

4. In cable conduits, the division plate adapted to be secured to'the bottom of the con- 0 duit and provided with the channel portion,

the sidethereof forming slot-irons, substantially as shown.

5. In combination with the yoke of a cableconduit, a division-plate secured thereto and 3 5 the lateral braces G, substantially as shown.

6. In cable railways, a conduit composed of yokes formed from a single bar or rail, said yokes having the central partition-plates secured thereto, the lateral extending arms of 0 said yokes having the chairs secured thereto, adapted to receive the track-rails, the angleblocks, the slot-rails, and the metal casing, all constructed and arranged substantially as shown and described. 5

In testimony whereof I affix my signature inpresence of two witnesses.

ZAOOUR PRALL BOYER.
